TROLLEY-GUARD.

Specification of Letters Patent.

Patented. June 25, 1907.

Application filed July 12,1906. Serial No. 325,863.

'mont, and State of Ohio, have invented cer tain new and usefulImprovements in Trolley- Guards, of which the following is aspecification.

My invention relates to new and useful improvements in trolleys, andmore particularly to a trolley guard; and it consists in the particularconstruction, arrangement and combination of parts which willhereinafter be fully described.

The object of the invention is to provide a simple, cheap, durable andefficient guard for preventing trolleys from jumping off the trolleywire.

A further object is to provide a trolley guard which serves the samepurpose when the car to which it is applied is reversed as whentraveling forward, and which may be applied to any ordinary trolleywithout requiring a change to be made in the harp or wheel. And a stillfurther object is to provide a guard which will readily pass throughswitches and under crosswires without interference.

In describing the invention in detail, reference is herein had to theaccompanying drawings, forming a part of this specification, in whichFigure 1 is a side elevation of the invention; Fig. 2 is a rearelevation of the same; and Fig. 3 is a cross section of the same.

Referring to said drawings, in which like reference numerals designatelike parts throughout the several views1 indicates the trolley harp and2 the trolley wheel, both being of an ordinary type of construction.Mounted in a substantially vertical position upon the wheel spindle 3 atopposite ends thereof close against the members 4 of the harp is alongitudinal arm 5. A diagonallyextending cross-channel 6 is provided inthe inner face of the arm 5 near its upper end,

' forming shoulders 7 which fit close against the opposite edges of themembers 4 of the harp, means being thus provided whereby the arms arerigidly held in substantially vertical positions. Carried by the lowerend of each arm 5 is an angular lug 8 having a vertical holetherethrough in which is slidably held the stem 9 of a spring-controlledelement 10 which lies close against said arm 5. Said element 10 consistsof a longitudinal body portion 11 having an integral head 12 with arounded edge 13. Provided in said body portion and head is alongitudinal slot 14 in which is held a rectangular block or slide 15which is carried by the spindles 3, said block or slide being adaptedfor guiding said head vertically in its movements, as will hereinafterbe explained. The spindle 3 projects outward beyond the slotted elements10 and has threaded upon its ends securing-nuts 16, as shown.

A coil-spring 17 encircles each stem 9, the lower end of said springresting upon said lug 8 and the upper end of said spring resting againstthe lower end of the body portion 11 of the element 10, whereby saidelement is normally held in an elevated position, as shown in full linesin Fig. 1.

The heads 12 project vertically above the wheel 2 at opposite sidesthereof, and are each provided with an inwardly-directed beveled lip 18at a point above the edge of the wheel, said lips being adapted to beengaged by the trolley wire when it slides from the wheel and to thusguard against the trolley leaving the wire.

As is apparent, when the heads 12 come into contact with a cross-wire, asupportingwire, or a trolley wire at a switch, said heads are therebyforced downward against the tension of the springs 17, permitting thetrolley to unobstructedly pass thereunder.

Owing to the fact that the tension of'the spring 17 is but little morethan sufficient to normally hold the head 12 elevated above the trolleywheel, a slight pressure upon the rounded edge 13 at any point issufficient to force said head downward to a level with the trolleywheel.

The movement of the element 10 being vertical, and the edges 13 beingrounded, the device works the same whether the trolley be travelingforward or rearward.

The opposite elements 10 being in nowise connected, said elementsoperate independently of each othera feature which is particularlydesirable in a device of this character for obvious reasons.

spirit or scope thereof. I do not, therefore, desire to limit myself tothe precise construction and arrangement of parts herein shown anddescribed.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a device of the character described, the

combination with a trolley wheel, a wheel sumac a ide-block carried bythe spindle and sli able in said slot, a stem carried by the lower endof the body portion, the lower end of said stern being movably held inthe hole in the lug, a coil spring carried by said stem between saidbody portion and said lug, a head carried by said body portion, saidhead being normally held with its upper edge elevated above the trolleywheel, said upper edge being rounded, and a beveled inwardlydirected lipcarried by said head above the edge of sald wheel, substantially as andfor the purposes set forth and described.

In testimony whereof I affix my signature in presence of two subscribingwitnesses.
